TECHNICAL FIELD OF THE INVENTION
The present invention provides various electric components on a seat body that can be moved by a slide rail in the front-rear direction in a vehicle, and wiring on a seat body side connected to the electric components and wiring on a vehicle body floor side connected to a power supply. And a power supply system for a slide sheet for an automobile, which is connected by a power supply cable.
[0002]
[Prior art]
Some automotive seats are equipped with electric components such as electric slide, reclining, lumbar support, side support, psy support, high adjuster or side airbag module, headset, air conditioner, position sensor, and body pressure sensor in the seat body. is there. The power supply equipment for the electrical components is configured by using a vehicle-mounted battery or a capacitor as a power supply, and connecting a wiring on the vehicle body floor side and a wiring on the seat body side continuous from the power supply with a power supply cable.
[0003]
2. Description of the Related Art Conventionally, as a power supply cable for an automobile slide seat, it has been proposed to connect a wiring on a vehicle body floor side and a wiring on a seat body side with a flat cable that can be flexibly deformed (Patent Document 1). The flat cable is curved from the end connected to the wiring on the seat body side to the end connected to the wiring on the vehicle body floor side, and is kept in shape. The end side connected to the wiring on the vehicle floor side is a slide rail. It is provided so as to extend in a parallel direction above the slide rail because it is held by a support that rises upward.
[0004]
In the automobile slide sheet, the support itself that holds the end side of the power supply cable connected to the wiring on the vehicle body floor side upward, and the wiring from the vehicle body floor side to the end side of the power supply cable held by the support tool This hinders effective use of the space under the seat cushion. At the same time, since the flat cable is exposed to the outside, foreign matter such as dust may adhere thereto, or a sharp article such as the tip of an umbrella inserted into the lower space of the seat cushion may damage the flat cable.

I have. With the guide bars 51a, 51b, 52a, 52b, the shutter 6 is assembled so as to be slidably supported in a stable manner. The guide bars 52a and 52b may be provided so as to protrude from the lower side of the rail side surface inside the cable routing rail 5.
[0016]
The power supply cable 4 exposes the coupler 4a connected to the wiring 2 on the vehicle body floor side to the side surface of the cable routing rail 5 and pulls the streak portion from the end side into the cable routing rail 5 so that the shutter 6 It is arranged inside. The end connected to the wiring 3 on the seat body side is inserted into the upper surface of the shutter 6 and arranged to be led out of the slit 50 of the cable routing rail 5 to the outside. The coupler 4b at the leading end is held by a bracket arm 1c on the upper side 1b (see FIG. 1).
[0017]
In the power supply equipment for a slide sheet for an automobile configured as described above, the slit 50 of the cable routing rail 5 is covered by the upper surface portion of the shutter 6, and the power supply cable 4 is moved by the movement of the shutter 6 accompanying the movement of the position of the seat body S. It is provided so as to be driven along the slit 50 of the cable routing rail 5. As a result, the power supply cable 4 does not hinder the undercarriage, does not hinder the effective use of the lower space of the seat cushion, and prevents sharp points such as the tip of an umbrella from entering, thereby improving the appearance. I can keep it.
[0018]
Instead of holding the coupler 4b of the power supply cable 4 with the bracket arm 1c on the upper side 1b, a coupler holder 7 can be provided and held on the upper surface of the shutter 6 as shown in FIG. The coupler holder 7 includes a receiving frame 7a into which the coupler 4b can be fitted, a locking claw 7b protruding downward from the front and rear of the receiving frame 7a, and a pressing lid 7c extending right and left of the receiving frame 7a. Have been.
[0019]
In the case where the coupler holder 7 is provided, the coupler 4b is projected out of the long hole 6d of the support plate 6c connected to a part of the shutter 6, fitted into the receiving frame 7a of the coupler holder 7, and latched as shown in FIG. The pawl 7b is attached by being fitted into the receiving hole 4d of the overhanging edge 4c. Further, the elongate hole 6d of the support plate 6c is covered with a holding lid 7c, so that the coupler holder 7 is assembled as a shutter cap.
[0020]
Instead of having a shutter 6 and a separate coupler holder 7, a support plate 7 b ′ having a receiving frame 7 a ′ into which a coupler 4 c can be fitted as shown in FIGS. 6 and 7 is connected to a part of the shutter 6. By doing so, it is directly assembled as a coupler holder 7 '.
[0021]
When the coupler holders 7 and 7 'are provided, the striations are drawn into the cable routing rail 5 from the end side connected to the wiring 2 on the vehicle body floor side and connected to the wiring 3 on the seat body side. The power supply cable 4 ′ can be easily assembled so that the power cable 4 ′ is inserted into the upper surface of the shutter 6. When the coupler holders 7 and 7 'are provided, the coupler 3b provided on the wiring 3 on the sheet body side may be held by the bracket arm 1c on the upper side 1b.
[0022]
The power supply system for the vehicle slide seats is equipped with multiple rows of rear seats for RVs and other vehicles as second and third seats. To secure luggage space in the car, the seat cushion is flipped up with the seat back vertically to secure each space. The seat body is mounted on a slide rear seat that can be moved to one side behind a front seat or a rear side in a vehicle by a long type slide rail.
[0023]
As the power supply cable, a cable that can adjust the length from the long type slide rail to the wiring 2 on the vehicle body floor side and the wiring 3 on the seat body side may be provided. For example, it is possible to provide a straight cord or a flat cable that can be bent and deformed, a curl cord that can be extended and contracted in length, and a reel winding cord that can be adjusted in length.
[0024]
As shown in FIG. 8, a required number of straight cords 4 ′ are bundled and held by the cable holder 8 as the power supply cable. The cable holder 8 is assembled from a plurality of receiving pieces 8a having a substantially rectangular cross section. The receiving piece 8a overlaps the adjacent one another with a semicircular projecting edge 8b and a recessed edge 8c, and projects a support shaft 8d rising from the recessed edge 8c and fits it into a receiving hole 8e of the edge 8b, so that the striations are curved. Assembled into a deformable chain.
[0025]
When the cable 6 is provided with a straight cord 4 'to be inserted and held by the cable holder 8, the shutter 6 is installed up and down on the front and rear sides of the cable routing rail 5 so as to be able to run as shown in FIG. The wire portion 2 is bent laterally from the end portion connected to the wiring on the seat body side toward the end portion connected to the wiring on the vehicle body floor side to form a shape, so that the wiring 2 on the vehicle body floor side and the seat body are bent. What is necessary is just to connect with the wiring 3 of the side.
[0026]
The straight cord 4 'is entangled with the position of the seat body, as shown in FIGS. 10 and 11, the curved line of the cable holder 8 changes its curved position while being driven, as shown in FIGS. The length of rotation can be adjusted by the follower curve of the cable holder 8 without the need. For this reason, it is possible to reliably prevent the power supply cable from being entangled or the like due to excessive hanging, and to stably move the power supply cable as the seat body moves.
